CONCRETE BUILDING CONSTRUCTION.

Application led March 26, 1928. Serial No. 264,619.

This invention relates to concrete building construction, and pertains particularly to such construction wherein the walls are formed as monolithic structures by successive pourings of concrete. It is concerned with method and devices employed in conjunction Vwith the use of so-called slip forms of the type wherein the forms which constitute the mold faces for the wall surfaces are elevated from time to time during the building up of the wall, to receive the successive pourings of concrete. The invention is concerned primarily with method and devices for the positioning and embedding in the concrete wall, in the course of its erection, of anchor members adapted to form fastenings or connections whereby metallic structure members, or the like, may be aiiixed to the wall as for the supporting. canopies, joists or other parts of the building structure.

A general object of the invention is the provision of method and means whereby suitable anchor-ages may be provided in the concrete wall during the course of its erection,

in accurately definite location and relationship, without involving any interference or complications in the construction or handling of the slip forms.

Another object is the provision of such method and means which involves a minimum handling of part-s on the ob.

Another Objectis the provision o-f method and means which will provide an arrangement whereby the attachment of the desired structural members to the wall in accurate position and with secure connection is facilitated, and without requiring chipping of the wall.

Yet another object is the provision of such method and means which will obtain a secure embedding and bonding o-f the anchorage members in the wall.

Other and further objects will be pointed out or indicate-d hereinafter or will appear to one skilled in the art upon an understanding of the invention or its employment in practice.

4For the purpose of aiding in the explanation of the invention, we show in the accompanying drawing forming a part of this specification certain arrangements of means and apparatus whereby the invention may be utilized, but it is to be understood that these are presented for purpose offillustration only, as the invention is not to be regarded as limited to the yparticular structural forms here shown.

In said drawing y Fig. l is a part sectional elevation of a wall under construction, taken transversely of the wall, and showing the relationship of portions of the slip form and anchorage supports; f

F ig. 2 is a fragmentary horizontal section taken on substantially yline 2-2 of Fig. 1;

Fig. 3 is a transverse sectional elevation Vcorresponding to Fig. 1 but showing the wall portions in completed condition and a bracket attached to the inner wall, and

Fig. 4t is a fragmentary section illustrating a feature of the anchor support, same corresponding to a view taken at 4-4 of Fig. 1 but with the outer plate of the anchor support removed.

In many concrete buildings it is desirable to provide secure anchorage in the walls or other places fory theconnection of various structural members ofthe building. Such anchorages must be firmly seated in the wall and, if the connection of the supported members are to be accomplished satisfactorily,

such anchorages must be accurately positioned and must` be easily accessible. The

present invention provides 'an arrangement and a method of operation whereby these andy other important advantages are attained.

An understanding of the method and devices may be most clearly had by reference to the examples illustrated in the drawings.

In Fig. 1 is illustrated the relation of certain l parts at a certain pointin 'the erection of a double concrete wall, the reference numeral 10 designating one of the collateral wall portions and the reference numeral 11 the other. Portions of the slip form panels are designated 12, 14, 15 and 16, the two first indicated being the panels for the outer wall surfaces and the two last mentioned being form panels for the inner or adjacent wall surfaces which bound an insulating space between the Lby successive pourings to a point Where it Vis desired to provide connecting arrangement for a structural ymember or the like, an anchor supporting frame is positioned in the desired location on the Wall and in the mold cavity.y The form oit anchor supporting tramehere shownv comprises a back plate 18 and a tace plate 19, which are maintained in the desired parallel relationship by spacers 20, to torni a skeleton-like trame. ln the desired locations and relationships, the anchor i members or soclrets 21 are secured to the baclr plate 18. lThese anchor members or sockets are threaded internally to take stub bolts 22, Which are threaded therein and which have vtheir other ends of ypolyhedral form and seated in aperturesin' the tace plate 19. yllhe assemblingot these anchor supporting` trames iviththe anchor members and stub bolts is done in the shop, Where the Work may be accomplished with :facility and with accuracy. The tace and back plates and spacers preterably are Wood. rIhe completed assembly o the anchor-supporting frame and the anchoring members forms a rigid structure wherein the anchor members are retained deiinitely and accurately Vin place, and the Width ot the frame, longitudinally roi the anchor men bers, corresponding to the thickness ot the Wall in which the anchor members are to be embedded. So, the trame with its contained anchor members may be Vhandled e`ectivelj 7 and positioned with facility at the desired vposition in the mold cavity, the plates 18 and 19 cooperating With the opposite Wall forms as guides, whereby the socket members 21 are automatically given the proper location with respect to the thickness ot the Wall. llie 'pouring ot the concrete then proceeds in the usual iashiomthe concrete nding easy access into the space between the plates and around theV anchor members and stub bolts. The

lslip form is elevated from time to time as the Wall is built up. Thus, in the course of the procedure, all of the anchor members and stub bolts kare closely embedded and bonded inthe concrete.

After the Wall has been builtl up to the desired height, and it is desired to make the connection of a structural member, the face plate 19 is torn outathus leaving a depression in the ace ot'y the Wall, into Which depression tlie ends ot' the stub bolts project. rlliese'bolts are then engaged by a suitable wrench and screwed out of the anchor members and Withdrawn from the Wall. rlhis leaves in the Wall openings through which the connecting bolts 2e may be inserted from the outside and screwed into the anchor inembers, said connecting bolts being equipped at their outer ends for the connection of a bracket 25, or other structural member, as by means ot nuts 26, and byivirtue of the deli* nitepositioning ofthe anchor members obtained by the procedure and meansabove described, accurate locating of the connection bolts is thus automatically attained, so that they will register properly in the bolt holes punched in the structural member in accord ance vwith. the predetermined design ot the structure. Thus the loss oi time and labor involved in chipping the concrete or specially 'punchin g the structural members is obviatcd. Y

Very secure anchorage and connection are obtained, as the anchor members are individually surrounded bv the concrete and bonded therein. The nature ot the anchor-supporting frame also accommodates the placing of reinforcing bars bot-h horizontally and vertically in the Wall and in any desired association withk the anchor members. The guiding cooperation ot the slip form with the traine insures the proper location of the anchor" members in respect to the Walls thickness, and the desired vertical position of the anchor frame may be maintained by suitable guidance on the Slip form trame.
